nano pi m4v2 rootfs crash problem

[mrigendra]

Buildroot image from Google Drive
https://drive.google.com/file/d/1zPgtH- ... sp=sharing

works.

But syncing buildroot from,
http://wiki.friendlyarm.com/wiki/index. ... for_RK3399

Doesn't work and have compilation issues.

So I git cloned uboot and kernel from

kernel:

git clone https://github.com/friendlyarm/kernel-rockchip --depth 1 -b nanopi4-linux-v4.4.y kernel-rockchip

export PATH=/opt/FriendlyARM/toolchain/6.4-aarch64/bin/:$PATH
make ARCH=arm64 CROSS_COMPILE=aarch64-linux- nanopi4_linux_defconfig
make ARCH=arm64 CROSS_COMPILE=aarch64-linux- nanopi4-images
make ARCH=arm64 CROSS_COMPILE=aarch64-linux- nanopi4-bootimg
built boot.img


uboot:

git clone https://github.com/friendlyarm/uboot-rockchip --depth 1 -b nanopi4-v2014.10_oreo
cd uboot-rockchip
export PATH=/opt/FriendlyARM/toolchain/6.4-aarch64/bin/:$PATH
make CROSS_COMPILE=aarch64-linux- rk3399_defconfig
make CROSS_COMPILE=aarch64-linux-

and then copied boot.img, uboot.img, miniloader.bin to extracted buildroot images and replaced. Created buildroot image
./mk-sd-image.sh buildroot

Then flashed
sudo dd if=out/rk3399-sd-buildroot-linux-4.4-arm64-20210706.img of=/dev/sdd bs=1M

But rootfs doesn't mount and it crashes.

What I am missing here,
1. initrd
2. root parameter, tried many parameters such as /dev/mmcblk0p1,p2, 1p7, 1p2 rootfs never mounts.
3. synced armbian image and that build system boots correctly.

Looks like these guys who made it are sleeping, anyways,

After some digging for buildroot I will suggest below method,
1. Don't sync with repo,
2. Download from google drive,

https://drive.google.com/file/d/1B4kl9h ... sp=sharing

this file, linuxsdk-friendlyelec-20190903.tar

Mind it its 8 GB file,

3. Solve compilation issues,
4. Issues are with

While building we will get many syntax errors, version errors, I changed like below and was able to build buildroot
./build.sh buildroot

Patches and issues. Copy these patches and apply with,

patch -p1 -i <patch> or make a patch file then put in respective package dir for automatically applied by buildroot,

A. qemu ( Path: linuxsdk-friendlyelec/buildroot/package/qemu)
delete the pre supplied patches, disable sha mismath error, then use 4.2.0 qemu version, upgrading qemu will give python errors =>3.6

Subject: [PATCH] gdbus: Avoid printing null strings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This mostly affects the 2.56 branch, but, given that GCC 9 is being
stricter about passing null string pointers to printf-like functions, it
might make sense to proactively fix such calls.

Then do some more changes as below.

[mrigendra]

After above fixes we get the final image. That image may not boot, so just to boot fully,(These are hacks not, use them if it doesn't boot with the provided uboot)

clone u-boot from this repo,

git clone https://github.com/friendlyarm/uboot-rockchip --depth 1 -b nanopi4-v2014.10_oreo
and rename it u-boot. Keep the original u-boot as backup.

In this uboot apply below changes,

Disable ramdisk failure and sha failure patch,

Now build wit

./build.sh all

Make flashable sd image,

sudo ./build.sh sd-img

Then flash

sudo dcfldd if=r<IMAGEPATH> of=/dev/sdX bs=1M sizeprobe=if

Once done,

sync & watch -d grep -e Dirty: -e Writeback: /proc/meminfo

Now SD card image should boot fully to GUI.
